I would also take a look at http://www.kuhne-electronic.de/ if a side =

They claim for their 144MHz transverter:

Specifications =20
Type TR 144 H =20
VHF Frequency range 144 ... 146 MHz=20
IF Frequency range 28....30 MHz=20
IF Input power 1....50 mW, internal adjustable attenuator | option 02: =
10...200=B5W=20
PTT control  contact closure to Ground=20
Output 25 Watt @ 50 Ohm IM3@20Watt 32 dB IM3@5Watt 39 dB=20
Operating voltage  13,8 V DC (12 - 14 V) =20
Current consumption  typ. 6 A =20
RX Gain typ. 15 dB output IP3 +11dBm=20
Noise figure  max. 0,8 dB NF=20
Dimensions mm  270 x 260 x 80=20
Case aluminium=20
IF connectors  BNC - female=20
RF connectors  N - female=20
DC supply and control connector SUB-D 9-polig =20

At EUR 995.00 (or c. EUR 858.00 without the 16% V.A.T.) this a rather =
expensive piece
of equipment.
